That is as I'd expect. Shift-selection should act like mouse selection, 
not like traditional C-SPC setting of mark then moving point.

Don't mix C-SPC setting of the mark and Shift-movement. Use one or the 
other.

Separating them like this is the only way to make Shift-selection act 
like users coming to Emacs from other programs expect it to.  Trying to 
kludge a solution where Shift-selection and C-SPC are interchangable 
breaks users' expectations, and if we do that, what is the point of 
enabling Shift selection at all?
